How to use a char to name an array?

I can't seem to find anything about this, I'm using a ton of arrays for an 8x8 LED matrix, and I need to make a bunch of arrays for everything, and I need to automatically name them, any help?

I am very unclear what you are asking. Can you explain by automatically naming them?

You cannot create and name an array based on the name of a variable. Why do you think you need to do this ?
